Airworthiness Directives; Air Tractor, Inc. Models AT-802 and AT-
802A Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) to 
supersede AD 2006-08-09, which applies to all Air Tractor, Inc. (Air 
Tractor) Models AT-802 and AT-802A airplanes. AD 2006-08-09 currently 
requires you to repetitively inspect (using the eddy current method) 
the two outboard fastener holes in both of the wing main spar lower 
caps at the center splice joint for cracks and repair or replace any 
cracked spar cap. Since we issued AD 2006-08-09, we have determined we 
need to clarify the serial numbers (SNs) of the Models AT-802 and AT-
802A airplanes affected by that AD. Additionally, we are adding an 
option of modifying the wing main spar lower caps to extend the safe 
life limit on the affected airplanes. Consequently, this AD would keep 
the actions of AD 2006-08-09, clarify the affected SNs, and add a 
modification option to extend the safe life limit. We are issuing this 
AD to detect and correct cracks in the wing main spar lower cap at the 
center splice joint, which could result in failure of the spar cap and 
lead to wing separation and loss of control of the airplane.

DATES: This AD becomes effective on July 28, 2010.
    As of April 21, 2006 (71 FR 19994, April 19, 2006) the Director of

SUPPLEMENTARY INFORMATION:

Discussion

    On July 31, 2009, we issued a proposal to amend part 39 of the 
Federal Aviation Regulations (14 CFR part 39) to include an AD that 
would apply to all Air Tractor Models AT-802 and AT-802A airplanes. 
This proposal was published in the Federal Register as a notice of 
proposed rulemaking (NPRM) on August 6, 2009 (74 FR 39243). The NPRM 
proposed to supersede AD 2006-08-09 to clarify the SNs of the Models 
AT-802 and AT-802A airplanes affected by that AD. Additionally, we 
proposed to add an option of modifying the wing main spar lower caps to 
extend the safe life limit on the affected airplanes.

Comments

    We provided the public the opportunity to participate in developing 
this AD. We received no comments on the proposal or on the 
determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed 
except for minor editorial corrections. We have determined that these 
minor corrections:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    We estimate that this AD affects 187 airplanes in the U.S. 
registry.
    We estimate the following costs to do the inspection:

----------------------------------------------------------------------------------------------------------------
           Labor cost                Parts cost        Total cost per airplane      Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
$500 to $800...................  Not applicable...                  $500 to $800            $93,500 to $149,600
----------------------------------------------------------------------------------------------------------------

     We estimate the following costs to do any necessary repairs for 
two spars that may be required based on the results of the inspection 
or the modification as an option. We have no way of determining the 
number of airplanes that may need this repair:

------------------------------------------------------------------------
                                                            Total cost
         Labor cost (two spars)             Parts cost      (two spars)
                                            (two spars)    per airplane
------------------------------------------------------------------------
225 work-hours x $80 per hour = $18,000.          $7,500         $25,500
------------------------------------------------------------------------

[[Page 35617]]

     We estimate the following costs to do any necessary spar cap 
replacement (two spars) that would be required based on the results of 
the inspection. We have no way of determining the number of airplanes 
that may need this replacement:

------------------------------------------------------------------------
                                                            Total cost
         Labor cost (two spars)             Parts cost      (two spars)
                                            (two spars)    per airplane
------------------------------------------------------------------------
495 work-hours x $80 per hour = $39,600.         $39,100         $78,700
------------------------------------------------------------------------

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, Section 106 describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this AD.

Regulatory Findings

    We have determined that this AD will not have federalism 
implications under Executive Order 13132. This AD will not have a 
substantial direct effect on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979); and
    3. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a summary of the costs to comply with this AD (and 
other information as included in the Regulatory Evaluation) and placed 
it in the AD Docket. You may get a copy of this summary by sending a 
request to us at the address listed under ADDRESSES. Include ``Docket 
No. FAA-2009-0707; Directorate Identifier 2009-CE-035-AD'' in your 
request.

2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2006-08-09, amendment 39-14565 (71 FR 27784, May 12, 2006), and adding 
the following new AD:

2010-13-08 Air Tractor, Inc.: Amendment 39-16339; Docket No. FAA-
2009-0707; Directorate Identifier 2009-CE-035-AD.

Effective Date

    (a) This AD becomes effective on July 28, 2010.

Affected ADs

    (b) This AD supersedes AD 2006-08-09, Amendment 39-14565.

Applicability

    (c) This AD affects Models AT-802 and AT-802A airplanes, all 
serial numbers (SNs) beginning with -0001, that are:
    (1) Certificated in any category;
    (2) Engaged in agricultural dispersal operations, including 
those airplanes that have been converted from fire fighting to 
agricultural dispersal or airplanes that convert between fire 
fighting and agricultural dispersal;
    (3) Not equipped with the factory-supplied computerized fire 
gate (part number (P/N) 80540); and
    (4) Not engaged in only full-time fire fighting.

Unsafe Condition

    (d) This AD results from our determination that we need to 
clarify the SNs of the Models AT-802 and AT-802A airplanes affected 
by AD 2006-08-09. Additionally, we are adding an option to modify 
the wing main spar lower caps to extend the safe life limit on the 
affected airplanes. We are issuing this AD to detect and correct 
cracks in the wing main spar lower cap at the center splice joint, 
which could result in failure of the spar cap and lead to wing 
separation and loss of control of the airplane.

    (5) If you have modified your airplane following paragraph 
(j)(1) of this AD prior to 3,200 hours TIS, you must do the 
following to reach the extended 8,000-hour TIS safe life:
    (i) If you did not cold work the outboard two fastener holes in 
both the left and right hand lower spar caps following paragraph 
(j)(2) of this AD, you must do the repetitive eddy current 
inspections following paragraph (j)(4)(i) of this AD until you 
accumulate 4,800 hours TIS after the modification on the wing spar 
lower cap. Upon accumulation of 4,800 hours TIS after the 
modification on the wing spar lower cap, do the repetitive eddy 
current inspections at intervals not to exceed every 600 hours TIS 
until you reach the extended safe life of 8,000-hour TIS.
    (ii) If you did cold work the outboard two fastener holes in 
both the left and right hand lower spar caps following paragraph 
(j)(2) of this AD, upon accumulation of 4,800 hours TIS after the 
modification on the wing spar lower cap do the repetitive eddy 
current inspections at intervals not to exceed every 600 hours TIS 
until you reach the 8,000-hour TIS safe life.
    (6) For the initial and repetitive eddy current inspections 
required in paragraphs (j)(3), (j)(4)(i), (j)(5)(i) and (j)(5)(ii) 
of this AD, follow the instructions as specified in Snow Engineering 
Co. Process Specification 197, page 1, revised June 4,
